    O experimento teve como objetivo avaliar o uso como probi贸tico de diversas cepas de microorganismos desenvolvidas em laborat贸rio. Foi usado o delineamento em blocos casualizados, utilizando 1600 aves sob os respectivos tratamentos: com antibi贸tico e sem probi贸tico; sem antibi贸tico ou probi贸tico; com probi贸tico A (L. fermentum LPB) e com probi贸tico B ("pool" de microorganismos). N茫o foram observadas diferen莽as significativas entre os tratamentos que continham ou n茫o antibi贸tico ou probi贸tico, sem preju铆zo ao desempenho dos frangos de corte. ABSTRACT An evaluation of the use of Probiotics developed at the Laboratory from many microorganism strains has been carried out. A total of 1600 broilers were used in a completely randomized block designed under four treatments: 1. Broilers treated with antibiotic but without probiotic; 2. Without antibiotic and without probiotic; 3. With probiotic A (Lactobacillus fermentum LPB); 4. With probiotic B (pool of microorganism strains: L. acidophillus, L. fermentum LPB, L. plantarum A6, Saccharomyces boullardii). No significant differences between the treatments with or without probiotics were observed in the results obtained which also showed no effect on the performance of the broilers
